Question
121, 118, 122, 115, 127,
112 Find the Wrong Number in the given number series ?Solution
ATQ, 121 – (3 × 1) = 118 118 + (3 × 2) = 124 124 – (3 × 3) = 115 115 + (3 × 4) = 127 127 – (3 × 5) = 112 Therefore, 124 should come in place of 122. The given series follows alternate addition and subtraction of consecutive multiples of 3.
2(3/4) of 2880 + 54% of 7520 - ? = 302
Find the value of the following expression:
372 ÷ 56 × 7 – 5 + 2
- What will come in place of (?), in the given expression.
(5³ + 3²) × 2 = ? (1225/25) - (192/96) + (50/5) = ?

What will come in the place of question mark (?) in the given expression?
(555 + 385 - 535) ÷ 15 X ? = 36 X 30
- What will come in place of (?), in the given expression.
75% of 640 – 20% of 150 = ? `(21 xx 51 + 54)/(9 xx 14 - 30 )` =?
95% of 830 - ? % of 2770 = 650
